how to compare data?

Expert Solution
Mainly while comparing two data set we can carry out it by 5 ways
1. The first comparison is based on graphical representation. We can draw suitable graphical diagram corresponding to the data sets.
2.we can compare the two data set by observing their mean/ median/ mode ( that is the measure of central tendency)
3.here we can compare the data set by calculating different measures of dispersion like standard deviations, quartile deviations ,range etc.if the data sets are having different unit we can also use relative measures of dispersion like coefficient of variation.
4. We can also compare the data sets by their respective skewness.computing skewness measures for the data sets.
5.another way out to compare the data sets is to observe their kurtosis. Wheather they are platikurtic or leptokurtic or mesokurtic or not.
These all type of comparison can be done by representing the data set in boxplot diagram.

Compare a data warehouse used for decision support to an
operational database. How do the data warehouse and the operational
database differ in their purpose, their structure, the technology
they use, and the way they are managed? Why would a company need
both?

The data below are comparisons of two different patches for how
well they repel mosquitoes. Compare the rates of mosquito
landings/hour for these two patches with the assumption that these
data are not normally distributed, with an α = 0.05. Which test
would be most appropriate? Provide critical value and calculated
test statistic, and then state your conclusion.

.How does cellphone service compare between different cities?
The data stored in CellService represents the rating of Verizon and
AT&T in 22 different cities (Data extracted from “Best Phones
and Services,” Consumer Reports, January 2012, p. 28, 37).
Is there evidence of a difference in the mean cellphone service
rating between Verizon and AT&T? (Use a 0.05 level of
significance)
